Abstract
A thin film transistor array substrate includes a base, a first metal layer having a gate electrode and a first insulating layer covering the base and the first metal layer. A semiconductor layer is formed on the first insulating layer facing but insulated from the gate electrode. The first insulating layer also supports a second metal layer having a source electrode and a drain electrode. A pixel electrode layer is electrically coupled to the source electrode or the drain electrode. A common electrode layer is insulated from the pixel electrode and is configured to receive a common voltage. A transparent conductive layer is formed on the base and is insulated from the pixel electrode. The semiconductor layer, electrically coupled to the source electrode and the drain electrode, is located between the source electrode and the drain electrode.
